I believed it is "401"
1-9 = 9 digits
10-99 = 90 which is 180
100-200 = 100 which is 300 digits
9+180= 189
1392-189= 1203
1200÷300=400 which 1200 digits
401 is the 1392 number scanned
168 is the answer to find the area
3rd tree = x
1st tree = 3x+50
2nd tree = 2x+100
3x+50 = 2x+100
subtract 50 from each side
3x= 2x+50
subtract 2x from each side
x = 50
so 3rd tree = 50 feet tall
Answer is B

Hope this helps in some way!
